TL;DR: In this paper, the authors present results on the equation of state in QCD with two light quark flavors and a heavier strange quark, and show that the effect of finite cutoff effects is significant for temperatures larger than about twice the transition temperature.

TL;DR: The first lattice calculation of the QCD phase transition using chiral fermions with physical quark masses using 2+1 quark flavors, spatial volumes between (4 fm) and (11 fm)(3) and temperatures between 139 and 196 MeV finds no metastability near the peak and a peak height which does not change when a 5 fm spatial extent is increased to 10 fm.
Journal ArticleDOI

TL;DR: In this paper, the transition temperature in QCD with two light and one heavier quark mass on lattices with temporal extent N_t =4 and 6.457(7) was calculated.

TL;DR: It is shown that for two degenerate flavors no finite-temperature phase transition is found for quark masses of {ital ma}=0.01 and 0.025, calling into question the existence of a QCD phase transition.
